Default why is 3x optical zoom the most common on digital cameras?

Looking at various brands of digital cameras, I have noticed that the lions share of cameras alll have 3x optical zoom..

Can anyone tell me why that is?

I would guess that it has to do with the cost of the optics. Larger zoom lens require more expensive optics.

I'm sure the price of the lens is part of it.

Another part is the viewfinder - it is diificult (expensive) to build a viewfinder that works at all well beyond about 100mm (equiv). Parallax is the issue. That is why you see don't see the "tunnel" viewfinders on cameras with long lenses: they all use an LCD (or its close cousin the EVF) or are SLRs (expensive) as a viewfinder. Lots of folks just don't like LCDs or EVFs as viewfinders.

Yet another trade-off.
